Abstract: A bullnose corner bead shear for making internal angle corner cuts to bullnose corner bead. The device includes a first cutting head having a first cutting member and a second cutting member, the first cutting member further comprising a cutting blade having a linear cutting edge portion and a curvilinear cutting edge portion, the second cutting member further comprising a cutting blade having a linear cutting edge portion and a curvilinear cutting edge portion, the first and second cutting member cutting blade curvilinear edge portions being contoured in such manner that they extend in a first direction distal of a line of the corresponding linear cutting edge portion and a second direction perpendicular to a plane of the corresponding cutting member, a handle assembly having a first handle and a second handle, the first handle being attachable to a first cutting member leg and the second handle being attachable to a second cutting member leg, and a pivot pin for pivotally attaching the first cutting member and the second cutting member such that when the first handle and the second handle are biased toward each other the first cutting member cutting blade cuttably engages the second cutting member cutting blade.
